R
is a tool for statistics and data modeling. R is a programming language and
software environment for statistical analysis, graphics representation and
reporting. The R programming language is elegant, versatile, and has a highly
expressive syntax designed around working with data. R is freely available
under the GNU General Public License, and pre-compiled binary versions are
provided for various operating systems like Linux, Windows and Mac.

R
provides a wide variety of statistical (linear and nonlinear modelling,
classical statistical tests, time-series analysis, classification, clustering)
and graphical techniques, and is highly extensible. .If you want to easily
manipulate your data and present it in compelling ways, R is the tool for you. This
programming language was named R, based on the first letter of first
name of the two R authors (Robert Gentleman and Ross Ihaka) and partly a play
on the name of the Bell Labs Language S. The S language is often the
vehicle of choice for research in statistical methodology, and R provides an
Open Source route to participation in that activity.

R
is an integrated suite of software facilities for data manipulation,
calculation and graphical display. The features are

an
effective data handling and storage facility

it
provides an unparalleled platform for programming new statistical methods in a
straightforward manner.

a
suite of operators for calculations on arrays, in particular matrices

in R
everything is an object, and has some object oriented programming capabilities.
